Hi all, I have problems burning/flashing the iTracker8211.
- OS: Linux/Ubuntu
- Segger J-Link JTag Debugger
- Arduino environment
- iTracker 8211 NBS
I try tu burn/flash the iTracker 8211 NBS. I followed the documentation (for arduino)
After “Verify and upload led_switch example” the iTracker isn’t detected any more as Bluetooth device and my upload-output says “Error: nRf52.cpu – clearing lockup after double fault”.
I also wondered why I do not have the “nRF5 Flash SoftDevice” option in arduino (which is shown in 4.3 Set the board and burn softdevice).
This is my complete debuging output:
This is my Pin connection:
GND -> pin 6
SWDCLK -> pin 9
SWDIO -> pin 7
Do you have any idea, what could be the problem ?
best regards, and many thanks in advance,
